What Mike said about subprocess. Also, in regular Python strings, \t means a tab character. You need to replace \ with \\ in the programme path ('c:\\test\\OpenProgram.exe 1 1') or use a raw string (r'c:\test\OpenProgram.exe 1 1'). (The r informs the Python parser that backslashes are to be used veratim, not as special code. If you're using Windows, raw strings make for fewer headaches when dealing with file paths.)
